UNIVERSAL PRESSURE SWITCH JPS WITH 2 SWITCHING RANGES
TECHNICAL DATA
APPLICATION
Housing colour and ma- terial:
steel plate, grey powder-coated Lower part = steel plate (galv. Zn bl) polyester fabric, coated on both sides
The JPS is a universal pressure switch with two switching ranges and is suitable für oil, water and air. It can also be used as a controller for domestic heating oil supply systems, pressure boosting systems, oil pumps and so on.
Membrane:
Ambient temperature: Medium temperature: Switch-off point: Protection rating: Switching capacity:
max. 55 °C
–30 to +80 °C
0.6–2.5 bar
IP10 according to DIN 40050 2A (2) 230 V – in accordance with DIN EN 61058-1
All devices have changeover contacts
Contact:
changeover switch
The starter button causes the second switching range to be bridged (if it functions as a safety range). The red indicator light remains illuminated until the accumulated pressure has reached the first switching range
Pressure ranges (setting ranges) and differentials:
(a) in the normal range: Switching range 1: can be set from 1.0 to 4.0 kp /cm² Differential can be set from 0.7 to 1.5 kp / cm² Switching range 2: can be set from min. 0.3 to max. 1.0 kp / cm² beneath the first range Fixed differential 0.3 kp /cm² (b) with increased pressure range : Switching range 1: can be set from 1.3 to 6.0 kp /cm² Differential can be set from 0.7 to 1.5 kp / cm² Switching range 2: can be set from min. 0.3 to max. 1.0 kp /cm² beneath the first range Fixed differential 1.3 kp /cm²
